Description

[0002] Petroleum hydrocarbons are a complex mixture of hydrocarbons, mainly composed of hydrocarbons, especially aromatic hydrocarbons and their derivatives. With the rapid development of the economy, petroleum hydrocarbon pollution has become a global problem. The frequent occurrence of oil extraction, smelting, transportation and various oil spills, as well as urban sewage and waste discharged from daily human activities, are all important sources of petroleum hydrocarbon pollution. Petroleum hydrocarbons contain volatile organic compounds, which are of various types and highly harmful. They can easily enter the human body through drinking water, breathing, detoxification and other ways, posing a huge potential threat to the human body and the biological environment. Therefore, it is very important to detect the content of volatile petroleum hydrocarbons (C6-C9) in water;

At the same time, the residual soil sample in the reaction tank is not completely cleaned up, and these residues may be mixed into the samples processed subsequently, resulting in cross-contamination or misjudgment, which will seriously affect the reliability and repeatability of the soil sample processing system, and further affect the credibility of the analysis results.
